Wavelet Transform of a analitic Signal

Started by Arnaldo Batista March 26, 2002
Hi there

Just tried the following:
I performed the scalogram (with a Morlet wavelet) of a signal. Then I did the
same, but with the hilbert transform of the same signal, which produced a
smoother scalogram. I am aware that the analytic signal as the negative
frequencies equal to zero. Is there any general advantage of using the analytic
signal for scalogram construction?
I used cwt from the matlab wavelet toolbox.
Thanks
Arnaldo
